Abstract
Water distribution networks were included in the catalogue of critical infrastructures by different institutions as the European
Council. One of the vulnerabilities of a water distribution networks consists of the contamination due to accidental or provoked
events. Therefore, it is increasingly common to develop water quality models which allow the study of these threats. Many hydraulic
models use algorithms with a high computational cost. Therefore, any strategy to accelerate these algorithms is an important
contribution to the problem. This paper proposes a method to simplify branched areas of the network without losing information
regarding water quality.
